The first series followed the unprecedented journey of Steven Avery— a convicted felon who was sentenced to life in prison for the murder of Teresa Halbech.

Over the course of 10 episodes, the show theorised that Avery had been framed by the local Wisconsin police for the killing and he was in fact innocent.

The show also followed Avery's nephew, Brendan Dassey who was also sentenced to life in prison after admitting he assisted his uncle with the murder. However, his confession was also later overturned and he was released from prison.

In the next ten episodes, Emmy Award-winning filmmakers Laura Ricciardi and Moira Demos return to the Midwest where they have exclusive access to Avery and Dassey, their legal team and family who are fighting for justice on their behalf.

“Steven and Brendan, their families and their legal and investigative teams have once again graciously granted us access, giving us a window into the complex web of American criminal justice,” Ricciardi and Demos said.

“Building on Part 1, which documented the experience of the accused, in Part 2, we have chronicled the experience of the convicted and imprisoned, two men each serving life sentences for crimes they maintain they did not commit. We are thrilled to be able to share this new phase of the journey with viewers.”

Part two will also introduce viewers to Kathleen Zellner— Avery's postconviction lawyer— as well as Laura Nirider and Steven Drizin, who work with Northwestern University’s Centre on Wrongful Convictions of Youth.
